These coins have essentially the same design as those found here, but adapted for printing flat on the bed instead of on edge. Despite the adaptation, the bottom printing only survived on the larger coins on my Replicator 2, your mileage may vary.Printed at 0.3mm, standard settings. If you print a full build plate make sure you have good adhesion, but I don't recommend printing directly on acrylic (too much damage on removal). Despite the fine detail on the tops of some coins they printed pretty well. I haven't loaded up filament to print anything but gold, but those are the most demanding of the designs and so I expect the others to do no worse.
